Abstract

Objective: To prepare the denture base material with anion-containing denture, and to test the friction properties of the denture base materials with different mass percentage of negative ion. Methods: Negative ion powders were added into the denture base materials by ball milling blending at 0%, 1%, 2%, 3%, 4% and 5%. According to oral denture base production process, the standard samples(19mm × 10mm × 4mm) were prepared and numbered. The experiment was divided into dry friction group and artificial saliva wet friction group. Each test group was tested for three times, and the mean value was calculated. Using scanning electron microscope (SEM) to observe the surface scratches of 0% wt, 2% wt, 5% wt samples. Results: Under the condition of dry friction, the volume wear rate decreased with the increase of the content of negative ion powder, the friction coefficient did not change significantly compared with the untreated group, the volume wear rate decreased under the condition of artificial saliva lubrication. The friction coefficient also did not change significantly. Compared with the untreated group, the SEM results showed that under the condition of dry grinding, the furrows and cracks on the surface of the sample were less, while under the artificial saliva lubrication condition, the surface of the specimen was smoother. Conclusion: The denture base material containing more than 2% wt of anion powder has good tribological properties.
